TECHNICAL FIELD

The present invention relates to the field of vaccines against Streptococcus pneumoniae.

BACKGROUND TO THE INVENTION

Streptococcus pneumoniae is a Gram-positive bacterium that is a major contributor to morbidity and mortality worldwide causing about 2 million deaths annually, i e the same range as for tuberculosis. Pneumococci are the major cause of common infections such as sinusitis, otitis, and community-acquired pneumonia (CAP), but also a common cause of severe invasive diseases (IPD) such as sepsis and meningitis. Young children and the elderly are the most susceptible age groups to acquire pneumococcal infections, but other factors such as underlying diseases, splenectomy, immunosuppression (including HIV), diabetes and a prior influenza-virus infection also sensitize for a pneumococcal infection. Pneumococcal infections such as CAP also predispose for cardiovascular diseases such as cardiac infarction, and meningitis patients may get neurological sequelae such as hearing loss and cognitive impairments.

Pneumococci have the human upper airways as their normal ecological niche, and up to 60% of preschool children may be colonized at any given time without symptoms. It is believed that most transmission events to the elderly come from young colonized children. S. pneumoniae is a highly genetically diverse species due to an efficient DNA exchange system resulting in a multitude of clonal lineages that may differ from one another in the presence and absence of genes and gene clusters, as well as in variations in individual genes. Variations in the capsular locus, the major virulence factor and vaccine target of pneumococci, have resulted in at least 97 known capsular serotypes with different potential of causing disease.

Pneumococcal conjugate vaccines (PCVs), targeting a limited number (7, 10 or 13 in PCV7, PCV10 and PCV13 respectively) of the known 97 capsular serotypes, have been introduced in the childhood vaccination program in many countries. Vaccine introduction has led to a decrease in IPD caused by vaccine-types in vaccinated children, however, non-vaccine type pneumococci have rapidly expanded and replaced vaccine-types in child-hood carriage and in IPD, but also in non-vaccinated population such as the elderly. Furthermore, protection against vaccine types differ, and for serotype 3, a serotype included in PCV13 and with a high mortality rate, there is more or less no evidence for protection against IPD so far. Data from Sweden, where both PCV10 and PCV 13 are used, show that serotype 3 was a dominating serotype among IPD cases during 2016, also in counties using only PCV13. Hence, novel vaccine approaches are needed.

In Sweden the total number of patients with IPD has remained almost the same after vaccine introduction. Moreover, in a recent study we found that pneumococcal carriage rates remained around 30% in the youngest children 8 years after vaccine introduction in Stockholm, and non-vaccine types were found in over 90% of the isolates. Antibiotic resistance is emerging among clinical pneumococcal isolates and according to reports from the European Centre for Disease prevention and Control (ECDC), and the European Antimicrobial Resistance Surveillance Network (EARS-Net), reduced susceptibility to penicillin has increased during the last years in Sweden and now exceeds 5% among IPD cases. In addition, the need for multiple antigens covering various capsular serotypes lead to high production costs for the known vaccines.

Opsonophagocytosis is the primary mechanism for clearance of pneumococci from the host, and the measurement of opsonophagocytic antibodies appears to correlate with vaccine-induced protection. However, it has proven difficult to design vaccines that elicit an efficient response in form of opsonophagocytic antibodies.

Taken together, the above issues stress the need for novel vaccine approaches. Thus, an object of the present invention is the provision of improved pneumococcal antigens able to confer serotype-independent immunological responses and/or improved response in terms of opsonophagocitic antibodies and protection in experimental models.

Background for Pneumococcal Microparticles

Spherical membranous blebs, so called outer membrane vesicles (OMVs), are produced by Gram-negative bacteria. OMVs range in size from 10 to 300 nm and they have been shown to be formed by budding from the bacterial outer membrane, and to have many functions, such as influencing virulence by different mechanisms. In Gram-negative bacteria OMVs have been suggested to act as vehicle to deliver virulence factors to host cells. Only recently, membrane vesicles (MV) were discovered also in Gram-positive bacteria and their formation and function is poorly understood compared to OMVs. Gram-positive bacteria do not contrain an outer membrane and the cell wall differs from Gram-negative bacteria.

For Streptococcus pneumoniae MV_(L) were isolated from pneumococci belonging to different serotypes (2, 6B, 8 and 23F) grown in liquid culture medium (1). MV_(L) from serotype 8 were shown to be protective against pneumococcal challenge with the same serotype in mice.

Importantly, no cross protection was shown to pneumococci of other serotypes.

Definitions

The pneumococcal capsule. The pneumococcal capsule, consisting of polysaccharide, exists in at least 97 different variants, so called capsular serotypes. The pneumococcal capsule is a major virulence determinant of pneumococci, affecting phagocytosis of the bacteria by host cells, and influence bacterial interactions with the innate immune response.

Pneumolysin (termed Ply herein) is a 53 kDa cholesterol dependent cytolysin released by Streptococcus pneumoniae upon lysis. It is one of the major virulence factors of this bacterium. It forms pores in all eukaryotic cells that have cholesterol in their membranes. The formation of pores by Ply frequently results in host cell death as membrane integrity is destroyed. Ply plays a central role in protecting the pneumococcus from complement attack and aiding its spread to other tissues/organs. Ply is able to activate the classical complement pathway, even in the absence of Ply specific antibody (2). A reference sequence from strain TIGR4 is presented in SEQ ID NO: 1.

LytA is the major autolysin of Streptococcus pneumoniae. Lysis is caused by cleaving the lactyl-amide bond between the stem peptides and the glycan strands of peptidoglycan, resulting in hydrolysis of the cell wall. The contribution of LytA to pneumococcal virulence is still unclear. It is possible that LytA-mediated lysis releases other virulence factors such as pneumolysin. LytA could also be released to lyse neighboring non-competent pneumococcal cells in a fratricidal manner. This would potentially facilitate genetic exchange between naturally competent pneumococcal populations that easily take up and incorporate DNA by homologous recombination. A third possibility is that LytA mediates lysis to release proteins involved in immune evasion or cell wall components that may interfere with the host immune response (3). A reference sequence from strain TIGR4 is presented in SEQ ID NO: 2.

PspC/CbpA (choline binding protein A) is a protein that binds the phosphocholine present in the teichoic acid and the lipoteichoic acid of the cell membrane and the cell wall. It is a major pneumococcal adhesin. It promotes pneumococcal adherence via a human-specific interaction with the ectodomain of the polymeric Ig receptor. It also prevents activation of C3b and complement-mediated opsonophagocytosis of pneumococci (4). The pspC locus is highly polymorphic and 11 major groups of this protein have been identified. Single PspC proteins are identified by sequential numbers separated from the group number by a dot (5) as follows: PspC1.1, PspC2.1, PspC2.2, PspC3.1, PspC3.4, PspC4.2/PspC10.1, PspC5.1, PspC6.1/PspC9.1, PspC7.1, PspC8.1, PspC11.1 and PspC11.4 (SEQ ID NOs: 3-14, respectively).

RrgB is the major subunit and stalk protein of the pneumococcal pilus. S. pneumoniae pilus 1 is encoded by a genetic islet (PI-1) present in 30 to 50% of the pneumococcal strains and is implicated in adhesion to epithelial cells, lung infection, and virulence. Pilus 1 is composed of the backbone subunit RrgB, the minor pilin subunits RrgA, and RrgC (6). A reference sequence from strain TIGR4 is presented in SEQ ID NO: 15.

RrgA is a minor pilin subunit of the pneumococcal pilus. RrgA is the tip protein of the pilus and has been shown to mediate adhesion to epithelial cells (6, 7). Recently, RrgA was shown to promote meningitis development in mice (8). A reference sequence is presented in SEQ ID NO: 16.

PhtD is a polyhistidine triad protein of S. pneumoniae. Polyhistidine triad (Pht) proteins are streptococcal surface proteins that contain multiple copies of a characteristic HxxHxH sequence, designed as histidine triads, which were predicted to bind divalent metal cations. Despite the increasing amount of biochemical, structural and physiological data, the functional role of PhtD and the other Pht proteins remains unclear. PhtD could be involved in zinc uptake. Alternatively, Pht proteins could play a role in protecting the pneumococcus from toxic effects of high Zn′ concentrations by scavenging, storing or trapping Zn′ ions (9). A reference sequence from strain TIGR4 is presented in SEQ ID NO: 17.

IgA refers to Immunoglobulin A1 protease of S. pneumoniae (10). Said IgA1-protease is a highly specific enzyme that cleaves amino acid sequences of certain proteins. The natural substrate of the IgA protease is immunoglobulin A1, hence its name. The enzyme is in fact capable of cleavage of proteins with the amino acid sequence N-X-Z-Pro-Pro/-Y-Pro-C, where the X in the sequence is preferably a Proline or Serine; the Y=Threonine, Serine or Alanine; and Z preferably is Arginine or Threonine. Thus, the IgA1 protease acts by cleaving the proline-rich hinge region of the heavy chain of IgA1. Release of the IgA1 protease by the pathogen allows adherence to mucous membranes by degrading host immunoglobulin A. A reference sequence from strain TIGR4 is presented in SEQ ID NO: 18.

The term protective immunity in the present context refers to immunization measures resulting in any degree of reduction in the likelihood of developing the condition for which the protective immunity is relevant, including a minor, substantial or major reduction in likelihood of developing the condition as well as total prevention. Preferably, the degree of likelihood reduction is at least a minor reduction.

The term sequence identity expressed in percentage is defined as the value determined by comparing two optimally aligned sequences over a comparison window, wherein a portion of the sequence in the comparison window may comprise additions or deletions (i.e., gaps) as compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity. Unless indicated otherwise, the comparison window is the entire length of the sequence being referred to. In this context, optimal alignment is the alignment produced by the BLASTP algorithm as implemented online by the US National Center for Biotechnology Information (see The NCBI Handbook [Internet], Chapter 16), with the following input parameters: Word length=3, Matrix=BLOSUM62, Gap cost=11, Gap extension cost=1.

DETAILED DESCRIPTION

The inventors isolated membrane vesicles (MV_(L)) from S. pneumoniae of serotype 4 grown in liquid cultures as previously described in the literature (1). They also isolated a novel type of membrane particles termed microparticles (MP) using a method involving growth of the bacteria overnight on blood agar plates. FIG. 1 shows the appearance of the MV_(L) and MP using electron microscopy and atomic force microscopy as well as their size distribution. Microparticles from S. pneumoniae TIGR4 grown on plates (MP) were smaller in size on average than MV_(L) coming from liquid media (MV_(L)). However, MP from S. pneumoniae serotype 3 display a different size distribution, containing less of the smallest particles and more of the largest ones.

Biochemical comparison of MV_(L) and MP preparations from TIGR4 revealed different properties for the MP and MV_(L). MP isolated from plates carried certain pneumococcal proteins to a higher extent than liquid grown MV_(L). They were particularly enriched in pneumolysin, the major pore-forming toxin in S. pneumoniae, as shown in FIG. 2D.

The novel MP were characterized using in vitro cell assays, and it was shown that consistent with the quantitated levels, the MP contain more biological pneumolysin activity than the MV_(L) (FIG. 3). It was further shown that the MP are taken up by epithelial cells (FIG. 4A-D) but are not cytotoxic (FIG. 4E). Using human monocyte-derived dendritic cells it was shown that both MP and MV_(L) are internalized into DCs, induce maturation of DCs (FIG. 5), and elicit differential cytokine responses (FIG. 6).

Next, the inventors investigated the potential of MP to protect mice using experimental models of pneumonia and invasive disease (FIGS. 7-11). The results showed that 80% of mice (wild type C57BL/6 mice) immunized with MP from serotype 4 (combined with aluminium hydroxide as adjuvant) survived after an intranasal pneumococcal infection caused by serotype 1 (heterologous challenge, cross protection). ELISA analysis showed that mice immunized with MP had a significantly higher MP-specific IgG response in comparison to control mice (treated only with the adjuvant) (FIG. 8). Immunization with serotype 3 and then challenge with serotype 3 led to a 100% protection (FIG. 11). Immunization with serotype 4 MP and then challenge with serotype 3 (a serotype that has been problematic in current vaccines) gave a protection of ca 50% (FIG. 11). Furthermore, immunofluorescence stainings showed that sera from mice immunized with MP from serotype 4 contained antibodies specific against multiple other serotypes, such as serotypes 1, 3 and 6B (FIG. 9).

In conclusion, it was found that MP protect mice against pneumococcal infection, and, most importantly, such protection is serotype-independent to a significant degree, in contrast to the protection conferred by currently available vaccines (polysaccharide or conjugated vaccines) that are, as mentioned in the background section, strictly serotype-dependent. The MP immunisation furthermore elicited protection against serotype 3 which is a challenge for current vaccines. Indeed, immunization with the currently clinically used vaccine PCV13 provided significantly less protection to mice than MP isolated from serotype 3 (FIG. 11).

Moreover, for protein based vaccines that are under development today, there is a problem in obtaining opsonophagocytic capability. Importantly, the present data show that using MP as a vaccine affects opsonophagocytosis (Example 3, FIG. 10). Last but not least, available pneumococcal vaccines (PCVs) are extremely important to fight pneumococcal diseases in developing countries. However, the costs to produce current vaccines are very high. An important benefit with the present approach is a drop in production costs since isolation of microparticles does not require high-cost preparations with conjugations, instead the method of the present invention is more simple based on bacterial growth combined with high speed-centrifugation.

Isolated Streptococcus pneumoniae Membrane Vesicles and Microparticles

As discussed in the Background section, a few types of Streptococcus pneumoniae membrane vesicles have been obtained in liquid culture (1). The solid phase culture method used by the inventors resulted in a novel type of particles termed microparticles having different and advantageous properties as discussed above and shown in the Examples. As shown in Table 1, the microparticles differ from the known membrane vesicles, MV_(L) in terms of relative protein expression.

EXAMPLES

The following examples are not to be regarded as limiting. For further information on the experimental details, the skilled reader is directed to a separate section titled Materials and Methods.

Example 1: Isolation and In Vitro Characterization of Novel Pneumococcal Microparticles

S. pneumoniae TIGR4 produces microparticles that differ depending on bacterial growth conditions.

Membrane vesicles were isolated and purified from Streptococcus pneumoniae serotype 4 strain TIGR4 grown in liquid medium (MV_(L)). Microparticels (MP) were isolated from pneumococci grown on blood agar plates. Preparations were analyzed by transmission electron microscopy (TEM) and atomic force microscopy, and revealed spherical bodies surrounded by membranous structures (FIG. 1A). The distribution of the size varied between MV_(L), MP from TIGR4 and MP from serotype 3 (FIG. 1B). In total 503 MV_(L), 378 MP from TIGR4 and 523 MP from serotype 3 were analyzed. As a control we also studied an isogenic pneumolysin mutant strain (TIGR4Δply) and found a similar size distribution. To reveal shedding of MV_(L) or MP from the surface of bacteria by TEM we then used an isogenic unencapsulated mutant in TIGR4 (T4R) grown in liquid culture. In the absence of the thick bacterial capsule, MV_(L) were clearly visible, emanating from the plasma membrane of S. pneumoniae into the extracellular milieu (FIG. 1C-D).

Proteomic Analysis Revealed Differences in Protein Content Between MV_(L) from Liquid Culture or MP from Plates

To analyze the protein content of both pneumococcal preparations, purified MV_(L) and MP were subjected to SDS-PAGE analysis. Distinct protein patterns in MV_(L) and MPs as compared with proteins present in whole cell lysates or bacterial supernatants (FIG. 2A), were identified. Interestingly, the proteomic content in MV_(L) and MP fractions differed, suggesting a differential enrichment of proteins in the different types of particles. We further conducted proteomic analysis using tandem mass spectrometry. In total, in TIGR4, we identified 317 proteins in MV_(L) (Table 3), and 216 in MP (Table 4), of which 184 proteins were found in both preparations. 133 proteins were unique to MV_(L) and 32 to MP (FIG. 2B). In serotype 3 we identified 462 proteins in MV_(L) (Table 5) and 344 in MP (Table 6). All detected proteins were further classified according to their subcellular localization based on the combination of LocateP and GO annotation (FIG. 2C) (11). A majority of the proteins identified in MV_(L) and MP were cytosolic proteins, followed by multi-transmembrane proteins, lipoproteins, N-terminally anchored proteins, secretory proteins and cell wall-associated proteins. While MV_(L) appeared to be more enriched in cytosolic protein and cell wall-associated proteins than MP from TIGR4, the latter harbored a higher percentage of multi-transmembrane proteins, lipoproteins, N-terminally anchored proteins and secretory proteins.

We further analyzed the mass spectrometry data in order to determine the presence of 30 known pneumococcal virulence factors in the particles. Both types of particles contained approximately half of these virulence factors present in TIGR4. Just two were unique to MV_(L), CbpD (12) and BgaA (13), and one to MP, IgA (10).

Based on the proteomic results, we next performed immunoblot analysis on specific pneumococcal proteins and virulence factors (FIG. 2D). Among cytosolic proteins we investigated the presence of the cytotoxin pneumolysin (Ply), which is a pore-forming toxin and one of the most important virulence factors in pneumococcal pathogenesis (2), GAPDH as a cytosolic marker (14), and LytA, the major autolysin of Streptococcus pneumoniae (3). The most striking observation was the high enrichment of Ply especially in MP, which also contained more LytA than MV_(L). Smaller differences were also observed in the enrichment of virulence factors belonging to other subcellular localizations. While MV_(L) displayed a higher amount of Pneumococcal surface antigen A (PsaA) (15) and Sortase A (SrtA) (16) than MP, the latter contained more Pneumococcal surface protein C (PspC) (17) and Polyhistidine triad protein D (PhtD) (9) (FIG. 2D). The major component of the pneumococcal pilus, RrgB (6), was equally found in both particle preparations.

These findings suggest the presence of a still uncharacterized mechanism for the selective secretion and enrichment of specific proteins and virulence factors of Streptococcus pneumoniae in these particle preparations.

A Biologically Active Pneumolysin was Found in Membrane Microparticles

The enrichment of Ply in both MV_(L) and MP prompted us to determine whether particle-associated Ply was functional and able to lyse erythrocytes in a hemolytic assay. For both types of particles we observed a dose dependent hemolysis (FIG. 3), however, Ply from MP showed higher activity than from MV_(L), which is consistent with the observation that MP contain more Ply. Notably, hemolysis seemed to be entirely caused by Ply, and particles prepared from a TIGR4 mutant lacking Ply (TIGR4Δply) exhibited no hemolytic activity.

MP are taken up by A549 epithelial cells, but are not cytotoxic.

MV in other Gram-positive bacteria have been described to function as vehicle to deliver vesicle-associated proteins to human cells (18) (19). To test whether pneumococcal MP can deliver pneumococcal proteins, we incubated MP from TIGR4 with A549 lung epithelial cells for 24 hours and visualized Ply and LytA by immunofluorescence staining (FIG. 4A-C). By analyzing orthogonal views of A549 cells treated with MP, we showed by immunofluorescence that MP can be taken up, with Ply and LytA detectable inside the cells (FIG. 4B-C).

To confirm our observation we further analyzed lysates of A549 cells treated with MP by immunoblotting with anti-Ply antibody (FIG. 4D). In order to minimize extracellular associated particles, treated cells were excessively washed before lysates were made. Consistent with our immunofluorescence results, western blotting revealed a dose dependent increase in Ply further suggesting that MP can be internalized.

Next we asked whether proteins associated with MV_(L) or MP, and in particular Ply, may contribute to cytotoxic effects on cultured human cells. To assess toxicity, A549 cells were treated with different concentrations of MV_(L) and MP for 24 hours, stained with fixable viability dye and analyzed by flow cytometry (FIG. 4E). The difference in cell death between samples incubated with MV_(L) or MPs and the negative control sample was not statistically significant, suggesting that Ply is not cytotoxic to the cells at concentrations present in MV_(L) or MP.

MV_(L) and MP are Internalized by Human Monocyte-Derived Dendritic Cells (DCs) and Induce their Maturation.

Since we found that MP can be internalized by epithelial cells, we then studied potential interactions of MV_(L) or MP with innate immune cells, focusing on DCs. First we assessed cytotoxicity by incubating DCs with MV_(L) or MP, stained with fixable viability dye and Annexin V, and then analyzed using flow cytometry (FIG. 5A). No significant increase in cytotoxicity was detected in samples incubated with MP, while addition of MV_(L) displayed cytotoxic effects at the two highest concentrations used. While both preparations were considerably less cytotoxic than live bacteria, with 70-80% cytotoxic cells after 24 hours of incubation, more studies are needed to assess the mechanism behind the increased cytotoxicity of MV_(L) from liquid cultures. Moreover, the percentage of apoptotic cells did not change after incubation with either of the particle preparations.

Then we investigated uptake of MP by DCs. First we incubated DCs with MP for 1 hour, lysed the cells and performed SDS-PAGE and immunoblotting on cell lysates to check for presence of Ply. Indeed, Ply was found in the cell lysates (FIG. 5B), suggesting that DCs internalize MP. Next, DCs were challenged for 30 minutes with inhibitors of actin polymerization and phosphatidylinositol 3-kinase (PI3K), cytochalasin and wortmannin, to block active phagocytosis, or with an inhibitor of lipid rafts, methyl-β-cyclodextrin, to block fusion of membranes. Subsequently, cells were incubated with MP for 1 hour, lysed, and the same protocol for immunoblotting was followed. Interestingly, blocking active phagocytosis or membrane fusion resulted in less Ply. However, when all inhibitors were used together, Ply still remained present in the lysates, suggesting either that the particles adhered to the cells or were internalized by another mechanism, not investigated in this study.

Taken together these data suggest that MP can function as a vehicle to deliver bacterial components to host cells. Since DCs are professional antigen presenting cells, we then assessed whether MV_(L) or MP could influence DC maturation. Cells were incubated for 24 hours with MV_(L) or MP, and then stained for MHCII and the co-stimulatory molecule CD86, and analyzed by flow cytometry (FIG. 5C). A dose-dependent increase in the presence of both markers on the surface of DCs was detected when cells were incubated with the particles. MV_(L) appeared to induce more maturation than MP, and similar levels of maturation were obtained with LPS.

MV_(L) and MP Induce Pro-Inflammatory Cytokine Responses in DCs

Since OMVs from Gram-negative have been shown to trigger a potent innate immune response (20) (21), we studied whether also pneumococcal MV_(L) or MP could affect pro-inflammatory cytokine responses. DCs we incubated with MV_(L) or MP for 24 hours, and ELISA assays were used on supernatants to determine concentrations of IL-6 (FIG. 6A), IL-8 (FIG. 6B), IL-10 (FIG. 6C) and TNF (FIG. 6D). MP induced release of IL-8 and low levels of TNF, while no induction was seen for IL-6 and IL-10. In contrast, MV_(L) induced all four cytokines tested to levels higher than live bacteria. None of the particles induced IL-1β or IL-12 (data not shown).

Example 2: Microparticles (MPs) Confer Serotype-Independent Protective Immunity

For each immunization experiment male C57BL/6 wild-type mice ca 5 weeks old were used. Before immunization, mice were anesthetized by inhalation of isofluorane (Abbott) and then intranasally administered with 50 μl/mouse of microparticles (MP) combined with the adjuvant aluminium hydroxide (Sigma Aldrich, 10 mg/ml in PBS) or the adjuvant alone for the control groups. Immunization was repeated again after two weeks from the first immunization following the same conditions described above. After 4 weeks of immunization, mice were infected by intranasal administration of 50 μl/mouse of 5×10⁶ CFU, for S. pneumoniae type 1 infection experiments (FIG. 7), or 10⁶ CFU, for S. pneumoniae type 3 infection experiments (FIG. 11).

All mice were anesthetized by inhalation of isofluorane prior to challenge with bacteria. After the infection, clinical symptoms of the mice were monitored multiple times per day (in accordance with the ethical permit). Blood samples (5 μl/mouse) were taken every day of infection and level of bacteremia was assessed by plating serial dilutions of blood samples onto blood-agar plates. Mice that reached humane end-points were anesthetized by inhalation of isofluorane and intranasal administered with 100 μl/mouse of the fluorescent marker Bacterisense 645 (Perkin Elmer) 30 minutes before the sacrifice. Prior to sacrifice, mice were anesthetized again (isofluorane inhalation). After sacrifice, mice were placed in the IVIS Spectrum Imaging System to detect the fluorescent signal of the bacterial infection. After the IVIS imaging, lungs and spleens were collected for further analysis. Bacterial amount in the lungs was assessed by CFU count of bacteria after plating serial dilutions of lung homogenates onto blood-agar plates.

Intranasal immunization with microparticles (MP) from a serotype 4S. pneumoniae increased survival after a challenge with serotype 1S. pneumoniae (FIG. 7A). The increase in survival was significant also in comparison to immunization with MV_(L). The immunization greatly reduced the bacterial load in the lungs of the mice surviving the challenge with serotype 1S. pneumoniae (FIG. 7B). Furthermore, mice immunized with serotype 3 MP and then challenged with serotype 3 bacteria showed 100% protection in the pneumonia model, higher than immunization with the currently available vaccine PCV13, which only conferred a protection of 75% in the model. Moreover, protection against pneumococcal infection was absent in mice lacking B cells, suggesting the involvement of an adaptive immune response with anti-pneumococcal antibodies (FIG. 11).

Example 3: Serotype-Independent Binding and Opsonophagocitic Activity of Antibodies Raised Against Pneumococcal Membrane Particles

Antibodies raised against the inventive MP from serotype 4 as antigen were reactive against Streptococcus pneumoniae of other serotypes, such as 1, 6B and 3 (FIG. 9). In other words, the MP were able to elicit production of serotype-independent antibodies, much more so than MV_(L) (FIG. 9B).

The production of anti-MP antibodies in mice was more efficient (in particular at time point 2 weeks) when the antigen was administered together with an adjuvant. However, satisfactory results were obtainable even without an adjuvant (FIG. 8). Moreover, antibodies in sera were able to bind both the encapsulated T4 (TIGR4) and the unencapsulated isogenic mutant T4R to the same extent, indicating that the antibody response was capsule-independent.

Importantly, the anti-MP antibodies showed opsonophagocitic activity, increasing adhesion of bacteria and killing of internalized bacteria by RAW murine macrophages (FIG. 10).

Materials and Methods Bacterial Strains and Growth Conditions.

In this study six strains of Streptococcus pneumoniae were used: TIGR4 or T4 (serotype 4) (22), its isogenic mutants lacking the cytotoxin pneumolysin (T4Δply) (23), the autolysin LytA (T4ΔlytA) (3), or the capsule (T4R) (24), ATCC 6301 (serotype 1) and 1-33 (serotype 3). Bacteria were grown in C+Y medium pH 7.9-8.0 (for serotype 4) or THY medium (for serotype 1 and 3) at 37° C. A spectrophotometer (Genesys 20, Thermo Spectronic) was used to follow the growth by monitoring the optical density (OD) at 600 nm.

Isolation and Purification of Membrane Vesicles (MV_(L)) and Microparticles (MP).

For isolation of MV_(L) from a liquid culture, pneumococcal strains (TIGR4, T4Δply or T4ΔlytA) were grown at 37° C. in C+Y medium, pH 7.9-8.0 until OD600 nm=0.9. The culture was then centrifuged (17,000×g for 30 minutes at 4° C.) to remove bacterial cells from the supernatant. The cell-free supernatant was filtered through a 0.22 μm filter (Sarstedt) and centrifuged (120,000×g for 2 hours at 4° C.) to sediment the vesicles. Pellets were washed twice in phosphate-buffered saline (PBS) and resuspended in PBS.

For isolation of microparticles (MP) from bacteria grown on plates, the pneumococcal strains were streaked on blood agar plates and incubated overnight at 37° C. with 5% CO₂. Bacteria were harvested from plates, resuspended in PBS and MP were pelleted following the same procedure as mentioned above.

Crude MV_(L)/MP preparations were further purified by density gradient centrifugation using Optiprep™ Density Gradient Medium (Sigma). Pelleted particle fractions were adjusted to 50% (w/v) Optiprep™ in a total volume of 2 ml and overlayed with one fraction of 30% (w/v) Optiprep™ (9 ml) followed by a fraction of 5% (w/v) Optiprep™ (3 ml). Gradients were centrifuged at 250,000×g for 3 hours at 4° C. and the first 4 ml on top, containing the particles, were collected. After 3 washes with PBS (250,000×g for 2 hours at 4° C.), pellets were recovered in PBS and stored at −80° C.

Electron microscopy. To visualize MV_(L) and MP on bacteria, S. pneumoniae T4R was grown in C+Y medium until OD₆₀₀=0.4 at 37° C. Bacteria were harvested by centrifugation for 10 min at 4,000×g, 4° C. and pellets were suspended in 100 μl PBS. Glow discharged carbon coated grids (Oxford Instruments, UK) were incubated for 1 min with a drop of bacterial solution or purified MV_(L)/MP preparation and negatively stained with 2% uranyl acetate in water (7 times for 10 sec). Specimens were examined on a FEI CM120 microscope operated at 80 kV. Images were collected with a side mounted camera MegaView III (Olympus Soft Imaging solutions).

Atomic Force Microscopy.

5 μl of MP samples isolated from S. pneumoniae were placed onto freshly cleaved mica (Goodfellow Cambridge Ltd., Cambridge, United Kingdom). The specimens on the mica were blot dried and placed into a desiccator for at least 2 h. Imaging was performed on a Nanoscope Illa (Digital Instruments, Santa Barbara) Atomic Force Microscope using Tapping Mode with standard silicon cantilevers oscillating at resonant frequency (270 to 305 kHz). Images were collected at a scan rate of 0.8-1.5 Hz, depending on sample number and the size of the scan. The final images were fitted in both axes and presented in a surface plot of the height mode.

SDS-PAGE and Western Blotting.

The total amount of proteins in purified MV_(L) or MP, lysates of A549 cells or dendritic cells stimulated with MV_(L) or MP were quantified with Pierce™ BCA Protein Assay Kit (Life Technologies). Samples containing equal amounts of total protein were resolved by SDS-PAGE using 4-12% Bis-Tris gels (Life Technologies) and transferred to PVDF membranes. Membranes were then blocked with 5% skim milk in PBS containing 0.1% Tween-20 and incubated with antibodies as indicated. For detection of pneumolysin a mouse monoclonal antibody (Abcam, final dilution 1:500) was used. Polyclonal GAPDH (1:2,000) and LytA (1:2,000) (3) antisera raised in rabbits were used. Rabbit polyclonal antibodies against PspC (1:1,000), RrgB (1:1,000), PsaA (1:25,000), PhtD (1:25,000) and mouse polyclonal antibodies against SrtA (1:500) were kindly provided by Novartis Vaccines and Diagnostics. As loading control for A549 cells and dendritic cell lysates, a mouse monoclonal β-actin antibody (Santa Cruz) was used as primary antibody. Anti-mouse IgG or anti-rabbit IgG conjugated to horseradish peroxidase (GE Healhcare) were used as secondary antibodies (final dilution 1:10,000). Blots were developed with Amersham™ ECL Plus Western blotting detection system (GE Healthcare Life Sciences), using a ChemiDoc™ XRS+ (Bio-Rad Laboratories).

Tandem Mass Spectrometry.

Proteins in MV_(L) or MP samples were reduced, alkylated and in-solution digested by trypsin according to a standard operating procedure. Thereafter the samples were purified by Pierce C18 Spin Columns (Thermo Scientific), dried and resolved in 0.1% formic acid. The resulting peptides were separated in reversed-phase on a C18-column and electrosprayed on-line to a Q Exactive Plus mass spectrometer (Thermo Finnigan). Tandem mass spectrometry was performed applying HCD.

Database searches were made using the Sequest algorithm towards a FASTA database including proteins from Streptococcus pneumoniae TIGR4. The search criteria for protein identification were set to at least two matching peptides of 95% confidence level per protein. Only proteins with a Sequest score above 20 were considered for analysis, to avoid the possibility of false positives.

Subcellular localizations of proteins were predicted using the algorithm of website Locate P (http://www.cmbi.ru.nl/locatep-db/cgi-bin/locatepdb.py) (11).

Hemolysis Assay.

Purified MV_(L) or MP were incubated in 96-well plates with blood from buffy coats (diluted 1:50 in PBS containing 1 mM dithiothreitol (DTT)) for 1 hour at 37° C. After 50 minutes 1% Triton X-100 in PBS was added to the positive control wells in order to lyse all the erythrocytes. Plates were then spun at 400×g for 15 minutes at 4° C.; supernatant was transferred to an optical plate and the optical density was measured at 540 nm.

A549 Cell Toxicity Assay.

A459 lung epithelial cells were grown and maintained at 37° C., with 5% CO₂ in RPMI medium (Gibco) supplemented with 10% (v/v) Fetal bovine serum (FBS) (HyClone). To assess MV_(L) or MP associated cytotoxic effects, 0.6×10⁶ A549 cells were seeded in 6-well plates and incubated overnight at 37° C. Cells were then washed with PBS and incubated for 24 hours with medium containing MV_(L) or MP at indicated concentrations. Washed cells were labelled with Fixable Viability Dye eFluor® 780 (1:50,000, eBioscience) for 30 minutes at 4° C. in the dark, in presence or absence of 0.02% NP40 (Sigma) as positive control, and fixed with 4% paraformaldehyde (PFA) for 30 minutes at room temperature. Next, cells were gently scraped into PBS containing 1% FBS and analyzed in a Gallios™ Flow Cytometer (Beckman Coulter).

A549 Cell Uptake Assay.

To assess MV_(L) and MP uptake by A549 cells via immunoblotting, 0.6×10⁶ A549 cells were seeded in 6-well plates and incubated overnight at 37° C. Cells were then washed with PBS and incubated for 24 hours with medium containing the particles at indicated concentrations. After washing, cells were lysed in RIPA buffer containing 1× protease inhibitor cocktail (Roche). Cell lysates were analyzed by SDS-PAGE and western blotting.

Immunofluorescence Microscopy.

A549 cells (6.25×10⁴) were seeded in 24-well plates with coverslips on the bottom of the wells, and incubated at 37° C. overnight. Cells were then washed, fixed with 4% PFA for 30 minutes and permeabilized with 1% Triton X-100 in PBS for 5 minutes. MV_(L) or MP were detected with mouse monoclonal anti-Ply (1:200) and polyclonal rabbit antibodies to LytA (1:200). Respective antigens were visualized with Alexa Fluor® 488-conjugated goat-anti mouse IgG antibody (Life Technologies) and Alexa Fluor® 350-conjugated goat-anti rabbit IgG (Life Technologies) (1:1,000).

Actin cytoskeleton was stained with Alexa Fluor® 594 Phalloidin (Life Technologies, 1:40 dilution) for 1 hour and coverslips were mounted with Vectashield (Vector Laboratories, Inc.) on microscope slides. Images were acquired with a DeltaVision microscope equipped with a 60×-objective. Quick projection images of approximately 20 z-stacks were taken. Orthogonal views were used to visualize the cell monolayer from the x, y, and z axes.

After growth, pneumococci (serotypes 1, 3 and 6B) have been stained using the sera from the immunized mice as primary antibody (dilution 1:100 in PBS 1% BSA) and Alexa Fluor 488 goat anti mouse (dilution 1:500 in PBS 1% BSA) as secondary antibody.

Imaging has been performed with high-resolution Delta Vision Elite System using 100× objective (1000× total magnification). FITC Laser intensity 50%, exposure time 0.025 ms (FIGS. 13-15).

Quantification of the Signal Detected on the Bacteria after Immunofluorescence Staining

Using the functions Image>Adjust>Threshold and Analyze>Measure of ImageJ, the area covered by the bacteria and the area covered by the signal detected on the bacteria after staining with sera were selected, defined and measured. The final signal ratio was calculated by dividing the area of the signal (detected using the sera) by the total area of the bacteria.

Isolation and Differentiation of Human Monocyte-Derived Dendritic Cells.

Dendritic cells were isolated using RosetteSep™ Human Monocyte Enrichment Cocktail (Stemcell Technologies) according to the manufacturer's instructions. In brief, blood from buffy coats from healthy donors was incubated for 20 minutes with RosetteSep™ Human Monocyte Enrichment Cocktail (Stemcell Technologies), layered on top of Ficoll-Paque™ Plus (GE Healthcare) and centrifuged at 1200×g for 20 minutes without acceleration or brake. The monocyte containing layer was recovered, cells washed 7 times with PBS and passed through a 100 μm cell strainer. Monocytes were then differentiated for 6 days in RPMI containing 10% FBS supplemented with 37.5 ng/ml of Granulocyte macrophage colony-stimulating factor (GM-CSF) (Peprotech) and 37.5 ng/ml of Interleukin 4 (IL-4) (Peprotech), changing the medium after 4 days. For experiments, cells were resuspended in RPMI containing 10% FBS.

Toxicity and Apoptosis Assay of Dendritic Cells.

6×10⁵ cells were seeded in 96-well plates and incubated with RPMI containing 10% FBS and MV_(L) or MP at indicated concentrations, or with T4R in a multiplicity of infection (MOI) of 20, as positive control, for 24 hours. Gentamicin (100 μg/ml, Sigma) was added after 1 hour of incubation to stop bacteria from growing in samples stimulated with T4R. Before staining, cells were washed once in PBS and once in Annexin V Binding Buffer (BD Pharmingen). Staining was performed with Fixable Viability Dye eFluor® 780 (1:50,000, eBioscience) and FITC Annexin V (1:20, BD Pharmingen) for 30 minutes at 4° C., followed by two washes with Annexin buffer. Labelled cells were fixed in 4% PFA for 30 minutes, resuspended in PBS containing 1% FBS and analyzed in a Gallios™ Flow Cytometer (Beckman Coulter).

Activation Assay of Dendritic Cells.

6×10⁵ cells were seeded in 96-well plates and incubated in RPMI containing 10% FBS with MV_(L) or MP at indicated concentrations, or with 1 μg/ml lipopolysaccharide (LPS) (Sigma) as positive control, for 24 hours. Cells were stained with Phycoerythrin (PE) Mouse Anti-Human CD86 (BD Pharmingen) and PE-Cy™5 Mouse Anti-Human HLA-DR (BD Pharmingen) for 20 minutes at 4° C., washed twice with PBS and resuspended in PBS 1% FBS. Labelled cells were analyzed in a Gallios™ Flow Cytometer (Beckman Coulter).

Uptake Assay with Dendritic Cells.

10⁶ cells were seeded in 96-well plates and incubated with RPMI containing 10% FBS, in presence or absence of the inhibitors cytochalasin D (0.5 μg/ml, Sigma) and wortmannin (0.5 μg/ml, Sigma) (C/W), or methyl-β-cyclodextrin (MβCD) (10 μM, Sigma), for 30 minutes. Cells were then incubated with particles at indicated concentration for 1 hour and lysed in RIPA buffer containing 1× protease inhibitor cocktail (Roche). Cell lysates were analyzed by SDS-PAGE and western blotting.

Quantification of Cytokines.

Different cytokines were assessed (IL-6, IL-8, IL-10 and TNF) in cell-free supernatants of 10⁵ dendritic cells by Enzyme-Linked Immunosorbent Assay (ELISA), using commercially available BD OptEIA™ kits from BD Biosciences. Cells were incubated with particles at indicated concentrations, or with T4R or LPS (as previously described), for 24 hours.

Opsonophagocytosis Assay with RAW Cells.

RAW 264.7 murine macrophages were grown and maintained at 37° C., with 5% CO₂ in RPMI medium (Gibco) supplemented with 10% (v/v) Fetal bovine serum (FBS) (HyClone). To assess the opsonophagocytosis activity of antibodies in immunized mice sera 2×10⁵ RAW 264.7 cells were seeded in 24-well plates and incubated overnight at 37° C. Serotype 1 bacteria were incubated for 30 minutes at 37° C. with 5% CO₂ with 20% serum from mice immunized with MP+adjuvant, or with adjuvant alone as negative control. RAW cells were then washed with PBS and incubated for 1.5 hours with 2.5×10⁷/well of pre-treated bacteria. Cells were washed three times with PBS to remove unattached bacteria. To measure total uptake of bacteria, cells were incubated with a 50/50 solution of 2% saponin (Sigma) and trypsin-EDTA (Gibco) for 15 minutes at 37° C., to lyse eukaryotic cells, and total bacteria were plated for enumeration. To evaluate phagocytosis 300 μg/ml of Gentamicin (Sigma) and 0.12 mg/ml of Penicillin G (Sigma) were added to separate wells and incubated 15 minutes at 37° C., to kill extracellular bacteria. Cells were then washed three times with PBS and incubated with a 50/50 solution of 2% saponin and trypsin-EDTA for 15 minutes at 37° C. to lyse eukaryotic cells. To evaluate killing of bacteria inside macrophages separate wells were treated with antibiotics (as for phagocytosis), washed three times with PBS and then incubated for 1 hour at 37° C. with medium. Cells were then washed three times with PBS and incubated with a 50/50 solution of 2% saponin and trypsin-EDTA for 15 minutes at 37° C. to lyse eukaryotic cells.

Mouse IgG ELISA Assay.

To detect MV_(L)- and MP-specific mouse IgG in sera of immunized mice optical plates (Sarstedt) were coated with 1 μg/ml of MP in 0.1 M Sodium Carbonate buffer pH 9.5, overnight at 4° C. Wells were then washed three times with PBS containing 0.05% Tween-20 and incubated with PBS with 10% FBS, for 1 hours at room temperature. After three washes wells were incubated with mice sera diluted 1:500 in PBS with 10% FBS, for 2 hours at room temperature. Wells were then washed three times and incubated with anti-mouse IgG-HRP (GE Healthcare) diluted 1:500 in PBS 10% FBS, for 2 hours at room temperature. After three washes well were then incubated with TMB substrate (BD Bioscience) for 10 minutes and the reaction was stopped with 1 M H₃PO₄. Absorbance at 450 nm was then measured with a plate reader.
